Ultra-Low Phase Noise Oscillators

The Purest Frequency Source


Ultra-stable time and frequency signals

Cryoclock is the culmination of 20 years of research and now delivers the world’s purest microwave and RF signals in a reliable and autonomous package that is user friendly. Its output signals possess both ultra-low noise phase noise as well as ultra-high short and medium term frequency stability.

Our ‘turn-key’ products are continuously-operating, fully autonomous, self-contained, and do not require any cryogenics knowledge. It has a low maintenance cycle interval of 20,000 hours and includes monitoring software to ensure the device is operating perfectly and can recover from errors or power interruptions.

This product can be configured to provide multiple frequency outputs from X-band down to 1PPS including all the usual RF signals necessary for synchronisation.

Key applications:

  • Over the horizon radar​

  • Radio astronomy: VLBI, VLBA​

  • Deep space tracking and navigation​

  • Scientific frequency reference source​

  • Quantum computing systems

  • Data Centre and telecommunication networks


Ultra-Low-Noise Microwave Oscillator

The X-LNO is a microwave reference oscillator that produces world-leading ultra-low phase noise reference signal in the X-band region. By exploiting the remarkably high Q of sapphire, the oscillator delivers a +10 dBm signal with phase noise below -165 dBc/Hz at 10 kHz offset.

The X-LNO has a standard 3U package that is suited to rack-mounting although other OEM configurations are available on request. A key application for the X-LNO is the master oscillator in microwave communications and radar systems, including Precision Approach Radars and surface detection radars. The ultra-low phase noise of the X-LNO will enable significantly greater sensitivity in these radar systems when compared to quartz-based systems

This product can be configured to provide any frequency outputs between 8 to 12 GHz and wider ranges are possible on request.

Key applications:

  • Civilian and military radar​
  • Wind/gust monitoring near civilian airports​
  • Detection and tracking of fast-moving objects at a distance​
  • Identifying objects through Doppler signature​
